This paper analyzes the effect of immigrants’ networks on the decision of individual firms to starting exporting to the immigrants’ home country. Existing evidence on the trade-creating effect of immigrants show a robust effect, however at the national or regional level. Using French exports at the firm-level to 61 countries, I find that increasing the number of foreign immigrants in the region...

This study disentangles experimentally imitation, reinforcement, and reciprocity in repeated prisoners’ dilemmas. We compare a simple situation in which players interact only with their neighbours (local interaction) with one where players interact with all members of the population (group interaction). We observe choices under different information conditions and estimate parameters of a learn...

In this paper we study learning and cooperation in repeated prisoners’ dilemmas experiments. We compare interaction neighbourhoods of different size and structure, we observe choices under different information conditions, and we estimate parameters of a learning model. We test robustness of the estimator. We find that naive imitation, although a driving force in many models of spatial evolutio...

To resolve the phylogeny of the autochthonous mitochondrial DNA (mtDNA) haplogroups of India and determine the relationship between the Indian and western Eurasian mtDNA pools more precisely, a diverse subset of 75 macrohaplogroup N lineages was chosen for complete sequencing from a collection of >800 control-region sequences sampled across India. We identified five new autochthonous haplogroup...

England has very volatile house prices. Using survey data spanning multiple house-price cycles over nearly forty years, we document the association between house prices and homeownership at age thirty. We then use synthetic cohort methods to assess whether differences in early ownership rates persist in later life. We find that ownership rates at age thirty have varied substantially, with a sig...

We examine the effect of house price appreciation on bank loan portfolios during the 1996—2006 period. While most previous research in this area has concentrated on loan demand effects, we evaluate how house prices affect a bank’s credit supply. Controlling for possible simultaneity between house prices and bank loan portfolio growth, we find that banks affected by greater house price appreciat...

Experiences reveal that the monitoring costs of the foreclosure crisis may be nontrivial, and smaller governments may have more success at addressing potential negative externalities. One highly localized form of government is a homeowners association (HOA). HOAs could be well-suited for triaging foreclosures, as they may detect delinquencies and looming defaults through direct observation or m...

This paper examines the stable outcomes of organization choice between single-plant and multi-plant under asymmetric two regions. A typical implicit assumption on monopolistic competition models for trade and economic geography is that firms can produce and sell only at one place. This paper allows endogenous determination of the number of plants in a new economic geography model. In particular...

We develop an urban equilibrium job search model with employed and unemployed individuals where residential mobility of the unemployed is restricted. We assume a standard mono-centric model (firms are located in one location), but allow for imperfect labour markets. In contrast to models with perfect labour markets, the model predicts that the employed are only partially compensated for commuti...
